What are the steps to Install adialog instance - Java

I have installed the SCS, database and Central instance. They all work fine. I need to install a dialog instance on another LPAR (AIX).

1) Do I run the install from the server where i want the dialog instance or from the CI Server?

2) Do I need any filesystems mounted from the Central Instance server?

According to the documentation I would say no, but it asks you for the profile directory during the install.

3) Is there anything else I need to do to get the install going?

Once installed do I start it from the CI server using something like startsap all? If so how does the CI know about the DI instance?

Thanks
